Robert Heinlein was a science fiction author who wrote prolifically. I have read a few of his books, and they are both good and influential. 'A Stranger in a Strange Land' has been particularly lauded as capturing the zeitgeist of the 1960s. Here is a particular quote of Heinlein's I came across again:
"A human being should be able to: change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, pitch manure, solve equations, analyze a new problem, program a computer, cook a tasty meal, fight efficiently, die gallantly.Specialization is for insects!"
